6 RECEIVING AND PREPARATION PROCEDURE INSTALLATION 1) Remove shipping protection. 2) Inspect valve for transportation damage. 3) Inspect valve bore and remove any debris. 4) Cycle the valve inspecting the ball for coating damage. ACTUATORS WARNING! VALVES SHOULD NEVER BE USED AS A STRUCTURAL MEMBER. IMPORTANT! Valves mounted with electric actuators should be cycled to the mid-stroke position before cycling under power. CAUTION! Actuators are not to be mounted, removed, adjusted or re-installed to or from ValvTechnologies valves except by trained ValvTechnologies personnel. ORIENTATION CAUTION! Valves must be installed with the FLOW ARROW pointing from high to low pressure with the valve in the closed isolating position. Alternatively the high-pressure end will be labeled. The high-pressure end is defined as the end with the highest pressure, with the valve in the closed isolating position. NOTE: Uni-directional valves should not be installed in lines where a differential back pressure (from low to high pressure) of 200psi or more may exist. Page 6
7 WELDING, STRESS RELIEVING AND INSULATION The use of radiation shields is advised if heat damage to the actuator is a concern. Care is to be taken to minimize weld slag and splatter within the valve. Do not strike arcs on the valve. CAUTION! Valve must be OPEN during welding. CAUTION! Excessive temperature and incorrect insulating or stress relieving technique may damage the valve and void the warranty. 800 F MAX. Localized Stress Relief is acceptable, do not furnace stress relieve without consulting ValvTechnologies Engineering. DO NOT STRESS RELIEVE Only insulate to this level MAXIMUM 1100 F CAUTION! Valve insulation is prohibited during stress relieving. Valve service insulation is advised for valves expected to ex- CAUTION! No insulation is to be applied above the body flat. POST INSULATION PROCEDURES Piping system shall be cleaned and flushed. Limit switch and position indicator operation should be observed as the valve is cycled several times. CAUTION! Valves and valve assemblies should never be used as load bearing members or be used as part of a load bearing structure. Page 7
8 VALVE LUBRICATION ValvTechnologies metal-seated ball valve requires NO lubrication. Re-tightening of body (with system de-pressurized) and gland packing bolting is permissible, if leakage occurs in these areas. Required Torque values are given in Tables 1 & 2. OPERATION The use of Copper-Based Anti-Seize Grease for stud lubrication and Molybdenum Disulfide Anti-Seize Grease for packing lubrication is recommended. Bolt Tension may be decreased to 25% shown in Tables 1 & 2 when other or no lubrication is used. BOLT SIZE - INCHES (mm) TABLE 1 BODY BOLT TORQUE VALUES TORQUE ft/lbs (Nm) B7 OR EQUAL B8M OR EQUAL NOTE: Due to the ValvTechnologies valve s metal-tometal sealing surface operating torques are considerably higher than comparable soft seated ball valves. 5/16 (8) 12 (16) 4 (5) 3/8 (10) 18 (24) 6 (8) 7/6 (30) 29 (39) 9 (12) 1/2 (13) 45 (61) 13 (18) 9/16 (14) 50 (68) 19 (26) 5/8 (16) 85 (115) 26 (35) 3/4 (19) 150 (203) 45 (61) 7/8 (22) 240 (325) 70 (95) 1 (25) 355 (481) 110 (149) 1-1/8 (29) 510 (691) 155 (210) 1-1/4 (32) 700 (949) 210 (285) 1-3/8 (35) 950 (1288) 290 (393) 1-1/2 (38) 1250 (1695) 370 (502) 1-5/8 (41) 1600 (2169) 480 (651) 1-3/4 (44) 2060 (2793) 500 (678) 1-7/8 (48) 2500 (3390) 750 (1017) 2 (51) 3000 (4067) 900 (1220) 3 (76) (13965) 3100 (4203) 3-1/2 (89) (22371) 5000 (6779) STUD DIAMETER THREAD PITCHin (mm) TABLE 2 GLAND TORQUE NOMINAL BALL INSIDE DIAMETERin (mm) TORQUE VALUE in/lb (Nm) GLAND TORQUE NEVER EXCEED 5/16-18 (8) 5/8 (16) 48 (5.4) 60 (6.8) 5/16-18 (8) 1-1/16 (27) 48 (5.4) 60 (6.8) 3/8-16 (10) 2-1/8 (54) 84 (9.5) 105 (11.9) 3/8-16 (10) 3-1/16 (78) 84 (9.5) 105 (11.9) 3/8-16 (10) 4-1/16 (103) 84 (9.5) 105 (11.9) 7/16-14 (11) (14.9) 165 (18.7) 1/2-13 (13) 5-1/8 (13) 204 (23.1) 225 (25.5) 1/2-13 (13) 6-1/16 (154) 204 (23.1) 225 (25.5) 9/16-12 (14) (28.5) 315 (35.6) 5/8-11 (16) (44.8) 495 (56.0) Note: Values are for B8M, Class 1 bolting.

9 STEM ROTATION DIRECTION AND VALVE POSITION INDICATION All ValvTechnologies ball valves (unless specifically stated) are operated clockwise to close and counter-clockwise to open. 80 lbs. to CLOSE Typical valve hand wheels and levers require 80 lbf. (335N) of handle force to operate. Lever operated are shown to be open when the handle lies on the same axis as the valve bore. The valve indicated closed when the handle is at 90 o to the valve bore. The stem, gland and ball (and in some instances the drive sleeve) bear markings as shown to the left. The marks will line up on the left of a closed valve, when looking down on the stem and facing downstream. On actuated and gear-operated valves an arrow shows the valve position. ACTUATOR OPERATION Valve actuators must be installed, operated and maintained as per their manufacturer s written instruction. In the event of a conflict between these instructions and those contained in this manual an authorized ValvTechnologies distributor or to ValvTechnologies Houston facility should be contacted. The lubricant of worm gear actuators should be inspected every three months and be replenished or replaced if required. DISASSEMBLY MAINTENANCE WARNING! DISASSEMBLY AND REPAIR OF VALVTECHNOLOGIES VALVE ASSEMBLIES BY UNAUTHORIZED PERSONNEL MAY BE HAZARDOUS AND NEGATE WARRANTIES. CAUTION! During disassembly particular care should be taken not to damage mating, packing, or sealing surfaces. CAUTION! Packing must be replaced if gland nuts are loose. Only approved ValvTechnologies packing shall be used. Page 9
10 DISASSEMBLY (CONTINUED) 1) Valve shall be cycled closed. 2) Orientation and position shall be marked on valve components, particularly the side of the ball matched to the seat, prior to removal. 3) Marking should be indelible to the valve cleaning process, but should not damage the parts (i.e. NO STAMPING). CAUTION! Balls are matched to end caps these matched pairs should never be separated or interchanged. 4) Avoiding excessive force, remove the entire actuator assembly. 5) Remove body nuts and separate body and end cap. 6) Remove body seal or gasket, depending upon valve design 7) Remove body gasket. (if applicable) 8) Remove ball, after marking orientation and protect from possible damage. 9) Remove gland nuts, gland spring and gland. 12) Inspect ALL components, note defects and replace if required, then de-grease using a solvent in preparation for re-assembly. 10) Remove Stem. Page 10 11) Remove packing, using packing pick or equivalent.
11 CAUTION! Sand blasting is not permissible, as it may destroy or damage critical surfaces. REPAIR AND REWORK Prior to re-assembly all the following components should be replaced or inspected and verified as acceptable: Packing Body Gasket Belleville Spring Should be replaced if deformed or collapsed below the values of Table 3. Ball and Seat If no damage is evident the ball may be re-lapped to the seat, using methods outlined below: If ball/end cap cannot be re-lapped. The seat must be re-machined, re-coated and re-lapped to the new ball. This must be done by an approved ValvTechnologies facility. The seat may be re-worked several times, as a rework face tolerance is designed into the end cap. Contact ValvTechnologies for MOB Tolerance Ranges. Other Valve Components: In general these may be cleaned and returned to service. If rework is required, consult ValvTechnologies Engineering Department. The ball is lapped to the end cap using 3-micron diamond compound. Ball is moved in a figure of eight motion against the end cap. End cap is held and turned (at 30 r.p.m.) on a rotating table. If no rotating table is available end cap is to be placed on solid, clean surface and rotate by hand during lapping. The ball/end cap seal shall be tested by sliding the mating surface of the cleaned ball against the cleaned end cap seal ing area. If a visible unbroken band appears the seal is acceptable (as shown to the right).

Engineering approval is required prior to assembly. CAUTION! Only approved ValvTechnologies components should be used in the re-assembled valve. NOTE: It is recommended that all internal carbon steel valve parts and surfaces be coated with light motor oil. 1) Body is placed on its inlet flange, clamped hub or welded end with the body cavity facing up. 2) Stem shall be inserted through the stem hole from the body cavity side. 3) Stem is to be oriented so that tongue flats are parallel to bore. NOTE: The stems packing contact areas shall be coated with Molybdenum Disulfide Anti-Seize Grease. NOTE: Mark on top of stem should be on the left of the valve, when looking down on the stem and facing downstream. NOTE: Mark on gland will be on the left of the valve. 5) Install the gland springs with their conical ends facing each other. Gland springs are hand tightened. 4) Replace stem packing and gland. NOTE: Always coat both ends of gland nuts with a copper-based anti-seize lubricant to achieve correct stud tension and corrosion protection. Page 12
13 RE-ASSEMBLY (CONTINUED) 6) Force the stem against the body by using a stem jack. 7) Uniformly tighten packing gland nuts to the specified torque value (see Table 2). NOTE: A stem jack is a double nut stud or a soft (plastic or brass) object. Installing Actuator 8) Assemble actuator, lever and/or mounting bracket as necessary. Actuator and valve must both be in the closed position. CAUTION! Great care must be taken when reinstalling an actuator. The stem MUST be prevented from being driven into the ball. 9) All operator adapter plates supplied by ValvTechnologies have a machined hole in the middle of the plate. When this plate is mounted to the valve, it should be concentric with the shaft before the bolts are tightened holding the mounting plate to the valve. After tightening the bolts, the concentricity should again be checked. Any misalignment of the operator to the valve may cause binding in the operator, which may cause damage to either the valve or the operator. CAUTION! If the operator drive does not readily slip onto the valve, the stem, key and if necessary, drive sleeve should be inspected for burrs, etc. CAUTION! Only ValvTechnologies approved personnel should mount actuators. The valve MUST be tested after the actuator mounting process to verify zero leakage. 10) Remove Stem Jack. 11) Set operator closed stop with ball precisely in closed orientation. 12) Cycle the valve several times and re-torque the packing gland nuts. 13) Measure Critical Assembly Fit Dimensions Page 13
14 Pressure Seal Standoff NOTE: This measurement is only required on valves with a metal body seal. 14) Place body with end cap end up. Carefully align pressure seal parallel with body face. Very carefully place the end cap atop the body and pressure seal. All must be horizontal. 15) Check the body gap (pressure seal standoff). See Table 4. If the gap is out of tolerance, an oversized body may be used.

15 Lock-Up Gap for Large Bore Valves NOTE: For small bore (5/8, 1-1/16 and 2-1/8 ), low pressure (150# - 300#) valves, this measurement is not taken directly, but is calculated after measuring the spring standoff. Max. Feeler Gauge Thickness (F) 16) Place the upstream seat into the valve body with radius facing the opening, end cap end. 17) Insert the ball into the body, over the stem and onto the upstream seat. 18) Place the end cap carefully on the body and line up (parallel) with the body. Measure the lock-up gap (seat/ball gap without a spring). Lock-Up Gap Seat/Ball Gap = F x 1.4 (See Table 5 for limits) Body/End Cap Gap (H) Gauge Height (T) NOTE: If this measurement cannot be taken directly because of access, use alternative method, shown to the left. Lock-Up Gap (With Gauge) Seat/Ball Gap = T H (See Table 5 for limits) Belleville Spring Standoff 19) Measure Belleville Spring height. Refer to Table 3, for acceptable height range. If height is out of specification, replace with a new spring. NOTE: Some spring height is always lost due to set during first use. ValvTechnologies, Inc. recommends that the spring always be replaced during an overhaul. 20) Remove the end cap, ball and seat. 21) Insert the Belleville Spring with the large end resting in the body pocket. 22) Insert the upstream seat loose with the curved seat facing you, away from the Belleville Spring. Page 15

17 Complete Assembly 26) Remove the end cap and insert the body gasket/seal. 27) Recheck/re-inspect the sealing faces on ball, body and end cap to ensure they were not damaged during handling. 28) Replace all damaged body studs. Apply Copper-Based Anti-Seize Grease high temperature compound to the threads. 29) Replace Belleville spring, upstream seat and ball. Ensure the mate lapped side is facing the end cap in the valve body. 30) Insert the new ValvTechnologies body seal or gasket into the body, being certain that the top surface is precisely parallel with the body face. 31) Tighten the body studs/nuts evenly, observing the body gasket pull-down. Using gradually increasing torque levels, tighten opposite bolts using a star-like pattern until the body and end cap are pulled face-to face. CAUTION! Never turn a nut more than ¼ turn with out moving to a different body nut. 32) During the entire initial pull-down the two faces should remain precisely parallel. Failure to do so may result in a faulty seal. Torque in a star pattern to 1/3 of torque value listed in Table 1. Then torque in a star pattern to 2/3 of torque value listed in Table 1. Then repeat again at the full torque value of Table 1. For valves larger than 10 inches, repeat the last torque values (full torque). NOTE: THE STAR PATTERN IS EXTREMELY IMPORTANT. 33) Cycle the valve manually to verify that it is functioning correctly. 34) Re-torque the packing gland bolts evenly to the values given in Table 2. Page 17
18 TESTING 1) Valves may be tested in accordance with ValvTechnologies Quality Procedure, VQP ) When performing the seat test, the pressure must be applied on the upstream side. The arrow on the valve (or the label indicating the high pressure end) will indicate the direction in which pressure should be applied. NOTE: Bi-directional valves must be tested with consideration for the required reverse pressure sealing. Prior to any testing of bi-directional valves, a ValvTechnologies approved service center should be consulted to gain the correct test procedure and test pressure.
